Monteray cannot play PNG movies!?
I have a massive Photos library of green screen effects I've been collecting for years. I'm not a pro - I just enjoy making fun movies with my kids, etc. After updating to Monteray however, the majority of .mov files will not open in Quicktime or in iMovie! I can play them in VLC, but if I want to use them in iMovie that doesn't help me. I compared the ones that do work with the ones that won't, and it seems that if they are JPEG movies, they're okay - but PNG videos will not work. I feel sick about this.
I went back to an older MacBook Pro and they worked fine in QuickLook, but I did notice that opening them in QuickTime (or iMovie) actually converted them to a prores format. Why can't they be converted by the newer QuickTime? Is Apple making it LESS capable? I don't understand why they would do that. These were all free clips found on various websites that I'm assuming use png for a transparent background. Handbrake won't convert to ProRes. I don't know how I'm going to be able to use my thousands of video clips anymore if I can't batch convert them. It seems like a pretty ubiquitous format, so I don't understand why Apple doesn't support it...nor why there aren't tons of people complaining about this...
